This automotive
how-to guide was specifically written to assist owners of the 6th generation
(1997, 1998, 1999, 2000, 2001, 2002 and 2003)
GM Pontiac Grand Prix in unclogging and cleaning the air conditioner's
rubber elbow drain pipe which can cause a water leak on the passenger side
floorboard.

The procedure should be the same on other General Motors
vehicles especially those equipped with the GM 3800 Series II 3.8L V6 engine
such as the Bonneville, Oldsmobile Eighty-Eight, Chevrolet Impala, Monte
Carlo, Buick Regal, Riviera, Park Avenue, Le Sabre, Chevy Camaro, Lumina,
Pontiac Firebird, Olds Regency, and Holden Commodore.
